Once you've downloaded Viber, you will receive an access code via SMS or callback to activate Viber. The access code ensures that you are the real owner of the cellphone number you have registered and prevents others from obtaining your access code and placing calls with your caller ID.

"Last Online" indicates the last time you or your friend was available to talk through Viber.

You don't need to. Instead of searching for Viber contacts, let Viber do all the work for you! Viber uses your device's address book to automatically tag which of your contacts have Viber, and syncs your contact list each time your contacts are updated.
